Barnaby Joyce's book due in August

Barnaby Joyce has pleaded for privacy but he'll soon have a political memoir out after already taking $150,000 for a tell-all TV interview.

Weatherboard & Iron: Politics, The Bush And Me is due out in August and the publishers promise it will surprise readers.

The former Nationals leader quit as deputy prime minister after it was revealed he was having a baby with his staffer-turned-partner Vikki Campion.

"Joyce not only provides a context to this calamitous series of events but also offers an insight into the inner workings of politics and the media in this country," New Holland Publishers said.

"Coming so quickly after his public stoush with actor Johnny Depp, the High Court ruling that he was a dual citizen and his stunning victory in the subsequent by-election in the NSW seat of New England, Joyce was rarely far from the front pages of national and international news media."

The publishers promise the book will reveal what drove Mr Joyce during his career - "a career that is far from being over".

Mr Joyce recently called for changes to privacy laws after doing a $150,000 tell-all TV interview with Ms Campion.
